This product is a triangle bingo game, designed to review the basics of triangles. This is designed for a class size of 24 students. Each student in the class will write each of their classmates name in one of the bingo boxes, until all of the boxes are filled up (make sure they write in pen, so they can not change the names). The students are allowed a specified amount of time to complete the bingo questions, once the time is up as the teacher you will call on random students, if the students gets the questions right, then everyone can mark off that students name on their bingo card. Keep playing until there is at least one bingo. Usually I go until there is five bingo's, or until the more difficult questions have been answered.
